Yes, in many cases they do. If you are exporting dangerous goods (hazardous materials) internationally – for instance, a chemical manufacturer or pharmaceutical company shipping overseas – you will typically need to provide a 24-hour emergency contact number on the shipping documents. The exact requirements depend on regulations of the origin, transit, or destination countries and the mode of transport. For example, any air shipment of dangerous goods to or from the U.S. must include an emergency number per IATA rules (USG-12 variation). Many countries and carriers have similar rules or expectations. In short, including a 24/7 emergency number is considered best practice worldwide to enhance safety and compliance during international shipments.

The U.S. has one of the strictest, most clear-cut requirements (49 CFR 172.604) mandating a 24-hour number on all hazmat shipping papers. Internationally, regulations vary: there is no single global rule exactly like 49 CFR 172.604, but many countries have their own rules or adhere to certain standards. For example:

• Canada: Requires a “24-Hour Number” on dangerous goods shipping documents, similar to the U.S.
  
• Europe (ADR): No direct requirement on paperwork, but emergency info must be available (often via ADR instructions or SDS).
  
• IATA (Air): No universal rule except through state variations (like USG-12, CAG-09, etc.) for countries that require it.
  
• IMDG (Sea): Follows national competent authority requirements (e.g., shipments from the U.S. must comply with 49 CFR emergency number rule).
  
  In summary, the U.S. sets a uniform standard, whereas internationally you must navigate a patchwork of regulations. Best practice for global shippers is to include a 24/7 emergency number on all hazardous shipments, which keeps you in compliance wherever such info is needed.

In an emergency involving hazardous materials, time is critical no matter where you are in the world. An internationally accessible emergency number ensures that local responders can reach help immediately. If an incident happens in a foreign country, the responders there need to be able to call your emergency number without hassle (e.g. not struggling with foreign dialing formats or blocked toll-free lines). A globally reachable number, often accompanied by multi-language support, means the call will be answered quickly and information will be conveyed effectively. This is crucial for protecting lives, property, and the environment. In short, an internationally accessible 24/7 number is a key part of your hazmat risk management when shipping worldwide – it links the scene of an accident to the expertise needed to handle it, without geographic barriers.

It’s highly recommended. While not every regulation explicitly requires multi-language support, consider that an accident could occur in a non-English-speaking region. Having emergency responders and medical personnel understand the information is vital. If you’re a crop protection company exporting pesticides to Latin America or a pharmaceutical firm shipping chemicals to Asia, you’ll want anyone who picks up the phone to be able to communicate effectively with local responders. Therefore, choose an emergency number/service that can handle calls in the languages relevant to the countries you ship to. This ensures clear, accurate information is given during emergencies, which can save lives and prevent miscommunication-related delays.
